Ground Granulated Blast Furnace Slag (GGBS) is a cement substitute that improves durability and also the environmental credentials of concrete mixes. The activation of blast-furnace slag with alkaline liquids (e.g., NaOH or water glass) to produce alkali-activated slag cement has been studied during the past few decades. It is a recovered industrial by-product of an iron blast furnace. blast furnace slag for Portland cement, fi nely granulated blast furnace slag (MSJŠ) from the company Kotouč Štramberk, Ltd. was used. Because of its latent-hydraulic properties, granulated blast furnace slag (GBFS) has been employed as a cement component and as a concrete additive for more than 100 years. Anyhow, these cements still meets resistance, because of their reputation for requiring an extended curing duration. b. Their properties are similar to pure Portland cements and often beyond this. Ground granulated blast furnace slag is an eco-friendly material with regard to its production process and usage. It is a by-product of the iron-making industry. The process involves cooling of the slag through high-pressure water jets, this leads to formation of granular particles. The fi ner is the grinding of slag, the better are some properties, especially strength (primary, fi nal), workability (plasticity) and bonding. As there are many types of slag, it should be noted that the term ‘slag’ used throughout this publication refers specifically . Today, Lungmuß offers a complete product range for main, iron, slag and tilting runners. It employs 130 people across four sites in the UK: Scunthorpe, Wicken, Gurney Slade and Runcorn. Blast furnace slag cement (CEM III/A 42,5 R) A hydraulic cement produced by milling 20-80 parts (by weight) of Portland cement clinker together with a corresponding amount (80-20 parts) of blast furnace slag and a quantity of gypsum. GGBS offers a more sustainable concrete having higher compressive strength, reduced permeability and resistance to chloride and sulphate attacks.

Blast Furnace Slag in Cement and Concrete’ 1,10. optimum replacement of Ground Granulated Blast Furnace Slag Powder to cement without changing much the compressive strength is 15%. The amount of pozzolan shall be limited to 20% ±5% by weight of the portland-pozzolan cement for the types IP and IP-A. Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. Mit Flexionstabellen der verschiedenen Fälle und Zeiten Aussprache und … These amazing quality blast furnace slag cement are manufactured in a way that it adheres to the different types of materials to attach them together for solid construction. At Alibaba.com these blast furnace slag cement are tested at first to check their quality and durability. Ground granulated blast-furnace slag (GGBFS) Our slag cement CEMSlag TM is a hydraulic cement material created when granulated blast-furnace slag from the steel manufacturing process is ground to a fineness suited for concrete production. Modern cement production with tradition Cement Lime . Neighbor complaints are reduced or eliminated. For every tonne of GGBS used in a concrete mix, the embodied CO 2 levels are reduced by around 900 kg compared to the use of one tonne of traditional Portland Cement. An equipment fl owsheet of a grinding plant for granulated blast furnace slag is pre-sented in Figure 1. Enhanced Model and Simulation of Hydration Process of Blast Furnace Slag in Blended Cement Yao Luan1, Tetsuya Ishida2, Toyoharu Nawa 3 and Takahiro Sagawa4 Received 1 April 2011, accepted 4 October 2011 doi:10.3151/jact.10.1 Abstract A hydration model for cementitious materials was applied to slag blended cement. Rilem Publications, 2005. You can use these blast furnace slag cement in accordance with your usage. GGBS being a waste material, it needs proper method for disposal. In Blast furnace cement, the slag as obtained from blast furnace is used. Blast furnace slag cements are qualified for applications in nearly all fields of construction.
